Smartphones with automatic call recording without audible warning

Smartphones capable of recording calls without audible alerts from the other party are mostly Android-based models with proprietary interfaces from brands (Xiaomi, Poco, Redmi, Infinix, Tecno, Huawei, Honor), using their own dialer apps instead of the standard Google Dialer.

---

Brands and models with built-in recording

Xiaomi / Poco / Redmi: Records without warning if a regional firmware version featuring a proprietary dialer is installed (global versions often utilize the Google dialer with a warning).

Infinix / Tecno: Built-in automatic call recording is available out of the box in most regions.

Huawei / Honor: On many models, recording is available in the default settings or through official regional packages.

Samsung: Built-in recording is officially available, but in some regional firmware versions (e.g., for Russia and the EEA), it is hidden or requires a warning; changing the region via service software is needed.

Apple iPhone: Native call recording is not available out of the box due to strict limitations of the iOS system.

Wallet of Satoshi. Some troubles revealed

Wallet of Satoshi
App Version 3.3.6 (352), iOS 26.6

This complements the information from the WoS official website and I think may be useful to those who also encounter similar problems.

The custodial wallet runs with a direct connection with the Belarusian IP address. But the self-custodial wallet only runs via VPN! And I couldn't switch the wallet to non-custodial wallet without VPN.

---

Custodial Wallet

Switch between custodial and self-custodial wallet without VPN freezes at three-quarters part.

---

Self-custodial Wallet

Wallet of Satoshi stuck without VPN at startup during Syncing... at three quarters.
If self-custodial wallet was once initialized it is possible to return to custodial wallet by menu.

If self-custodial wallet was not once initialized on device, this state of the application can only be overcome either by restoring the self-custodial wallet of Satoshi, if it was already once created before, or by reinstalling the application.
Force-closing the app and restarting leads to nothing new, the app starts in the same state.

---

No or lost VPN

1. For example, if the connection requires VPN, Wallet of Satoshi displays a message: "Recovery Failed! Please check your 12 words and try again."
Green color indicates that the words are correct, there is a connection problem.
Turn on the VPN before starting the wallet recovery. If this status happened, the VPN will not help, restart WoS.
2. Red and green colors in the font can serve as a clue for an attacker while words brute force.

If the VPN connection is dropped or you disconnect, Wallet of Satoshi gives out the message: "A network error occured. Please check your connection."
The message disappears when the VPN is restored.

Switching from WoS Custody Wallet to Self-custodial wallet without VPN stuck the app on the Finalizing... at the eleventh of twelve parts of circle.

Air Barometer App by Maksym Buradchuk

Requires iOS 15.0 or later. Compatible with iPhone, iPad, and iPod touch.

Unlike most barometer apps that only display sea level pressure, this app can also show the actual atmospheric pressure at your current altitude. This makes the app closer to a real physical barometer and helps you better understand real local conditions.
The app also provides clear pressure charts, allowing you to track changes throughout the day and monitor long-term pressure trends.

Access to the barometer is handled differently in iOS. How apps obtain pressure data Direct sensor access: To read raw atmospheric pressure data from the built-in barometer, an app does not need the "Motion and Fitness" permission. Apple allows the use of the CoreMotion framework (specifically the CMAltimeter class) to obtain relative pressure without a system request. Why "Motion and Fitness" is needed: This permission is only required if the app wants to track steps, floors climbed, activity types (running, walking), or collect historical data about your movements in the background. Internet (weather): An app can also retrieve data from nearby weather stations over the network, but this typically requires access to your location (Location Services) rather than to the fitness features. How to check where the data is taken from Enable airplane mode: Disable Wi-Fi and cellular data. If the app continues to instantly respond to changes in altitude (for example, if you lift your phone from the floor to the ceiling) or updates pressure in real time, it's using the built-in barometer. Check your location: Go to Settings -> Privacy & Security -> Location Services. If the app has access to your location, it may be downloading weather and pressure data for your city from the internet.
